A conserved tetrapolar mating system permits sexual hybridization and recombinant host phenotypes in wheat- and barley-adapted Puccinia striiformis

This study shows that wheat- and barley-adapted Puccinia striiformis can sexually hybridize on a shared alternate host, producing progeny with novel host phenotypes.

A chromosome-scale, haplotype-resolved genome assembly of the barley stripe rust pathogen Puccinia striiformis f. sp. hordei

The paper presents a high-quality, haplotype-resolved genome assembly of the barley stripe rust pathogen Puccinia striiformis f. sp. hordei using long-read and Hi-C sequencing.

Long-term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

The paper tracks global spread and hybridization of wheat yellow rust pathogen, identifying nuclear reassortment and intercontinental movement as key drivers of evolution and disease impact.

The variable wheat stripe rust effector AvrYr7 evades Yr7 recognition through sequence and expression polymorphisms

The paper clones AvrYr7, an effector gene in wheat stripe rust, and identifies variants that evade recognition by the resistance gene Yr7 through sequence and expression differences.

Interspecies hybridization as a route of accessory chromosome origin in fungal species infecting wild grasses

The paper identifies a new accessory chromosome in Zymoseptoria tritici and shows it originated through interspecies hybridization with Zymoseptoria ardabiliae.

Rhizoctonia theobromae isolates causing Vascular-Streak Dieback of Cocoa and Cassava Witches' Broom Disease are likely host-specific, regionally divergent and homothallic

The study investigates Rhizoctonia theobromae isolates from cocoa and cassava diseases, finding host specificity, regional divergence, and homothallism.

Defence recognition of a stripe rust fungal effector is uncoupled from disease outcomes in wheat

The paper identifies an AvrPstB48 effector from stripe rust fungus that triggers defence responses in wheat but does not directly correlate with disease outcomes.

Long-read genomics reveal extensive nuclear-specific evolution and allele-specific expression in a dikaryotic fungus

The paper uses long-read genomics to study dikaryotic fungus genome biology, revealing nuclear-specific evolution and allele-specific expression.

Mating-compatibility genes employed as diagnostic markers to identify novel incursions of the myrtle rust pathogen Austropuccinia psidii

This study develops a diagnostic method using mating-type HD locus alleles to identify new incursions of the myrtle rust pathogen Austropuccinia psidii.

H4K20me3 controls Ash1-mediated H3K36me3 and transcriptional silencing in facultative heterochromatin

This study shows that H4K20me3 is essential for transcriptional silencing in facultative heterochromatin by maintaining Ash1-mediated H3K36me3 and affecting other chromatin marks in the fungus Zymoseptoria tritici.

Recent loss of the Dim2 DNA methyltransferase decreases mutation rate in repeats and changes evolutionary trajectory in a fungal pathogen

The paper shows that loss of Dim2 DNA methyltransferase in Zymoseptoria tritici reduces mutation rates in repeats and alters evolutionary trajectory by affecting 5mC levels and transposable element dynamics.

Dynamics of transposable elements in recently diverged fungal pathogens: lineage-specific transposable element content and efficiency of genome defences

The paper examines TE dynamics in Zymoseptoria species, finding recent insertions and varying Repeat-Induced Point mutation signatures across isolates.

Genome compartmentalization predates species divergence in the plant pathogen genus Zymoseptoria

The paper compares genome architecture across Zymoseptoria species, finding high conservation of compartmentalization despite genomic variability.

Destabilization of chromosome structure by histone H3 lysine 27 methylation

The paper investigates the role of H3K9me3 and H3K27me3 in genome stability in Zymoseptoria tritici, showing H3K9me3 maintains stability by preventing H3K27me3, while H3K27me3 promotes instability of accessory chromosomes.

Extraordinary genome instability and widespread chromosome rearrangements during vegetative growth

This study investigates chromosome instability in the fungus Zymoseptoria tritici, finding high rates of accessory chromosome loss and suggesting an adaptive role in virulence.

Extremely flexible infection programs in a fungal plant pathogen

This study examines how genetic diversity in Zymoseptoria tritici affects infection phenotypes, revealing significant gene expression variation and epigenetic regulation linked to transposable elements.
